I understand your position and I don't know that there's much point
arguing about the relative merits of customization.  We simply disagree.

I've read the documentation and seen bits of code (samples, examples, etc.)
written to use it.

Async RPC is another one of those religious issues.  My religion says
that they're a bad idea because they're hard to understand, represent
an unnecessary new aspect in the computing model, and that one should
use existing primitives for asynchrony (process) and communications
(procedure call) together to achieve the same effect.  And in anticipation
of the "but not all systems support cheap multi-threading" objection,
I'll say (a) let's fix that and not introduce new features, and (b) it
can't be that much harder to bring up a simple threading package than
it is to bring up the async part of an RPC system that support async
RPC and the return is much higher for doing the former than the latter.

NCS 2.0 supports callbacks to known procedures (i.e., not callbacks through
passed procedure pointers).  Our intention to to support callbacks in
general as part of the base system.

Authentication and privacy features are part of NCS 2.0.
